Passing data from parent to child components is fundamental for creating reusable Angular components and establishing proper data flow in component hierarchies. As the creator of CoreUI, a widely used open-source UI library, I’ve designed thousands of Angular components that rely on @Input properties for customization, configuration, and data sharing in enterprise applications. From my expertise, the most effective approach is to use the @Input() decorator with property binding. This method provides type-safe data flow, excellent component reusability, and clear parent-child communication patterns that scale well in large applications.

Passing props between React components is fundamental for creating reusable, modular components and establishing proper data flow in component hierarchies. As the creator of CoreUI, a widely used open-source UI library, I’ve designed thousands of React components that rely on props for customization, data sharing, and flexible API design in enterprise applications. From my expertise, the most effective approach is to pass props as attributes to child components and destructure them in the function parameters. This method provides clean component interfaces, type safety with TypeScript, and excellent developer experience with IntelliSense support.
